Each page below puts it next to one product you might be using today: features side by side, what a month costs with the provider's bill included, and a plain list of reasons to stay where you are.

Read the comparison →How these pages are written
Prices are dated and linked. Every number names the day it was read and the page it came from; Senlo's columns add your provider's bill so the totals compare like for like.
Senlo does not send mail. It renders, personalizes and decides; delivery is your Resend, Postmark, SES or SMTP account. Each page says so first, because for some teams that settles it.
Every page has a "stay with them if" list. SMS, broadcasts, A/B tests, inbound email: the other product often does more. If you need those, the page tells you.
Came here by provider, not by product?
If you already send through Amazon SES or Postmark and want a template editor and automations on top, these pages start from the provider.
